JMeter is a 100% pure Java desktop application designed to load test functional behavior and measure performance. It was originally designed for testing Web Applications but has since expanded to other test functions, including JMS, LDAP, SMTP, JDBC, SOAP etc. Release 2.1 includes an additional script format - smaller, more compact, more readable - based on Xstream. There are updates to the JMS, JDBC, WSDL and XML processing. Also a new config item, CSV DataSet for easier test parameterisation. For a full description, see the history of changes.
